Brad Fitzpatrick	becce82246	net/netns, misc tests: remove TestOnlySkipPrivilegedOps, argv checks The netns UID check is sufficient for now. We can do something else later if/when needed.	5 years ago
Brad Fitzpatrick	7a410f9236	net/netns: unindent, refactor to remove some redunant code Also: * always error on Control failing. That's very unexpected. * pull out sockopt funcs into their own funcs for easier future testing	5 years ago
Brad Fitzpatrick	45b139d338	net/netns: remove redundant build tag Filename is sufficient.	5 years ago
Brad Fitzpatrick	dcd7a118d3	net/netns: add a test that tailscaleBypassMark stays in sync between packages	5 years ago
Brad Fitzpatrick	1e837b8e81	net/netns: refactor the sync.Once usage a bit	5 years ago
Avery Pennarun	e7ae6a2e06	net/netns, wgengine/router: support Linux machines that don't have 'ip rule'. We'll use SO_BINDTODEVICE instead of fancy policy routing. This has some limitations: for example, we will route all traffic through the interface that has the main "default" (0.0.0.0/0) route, so machines that have multiple physical interfaces might have to go through DERP to get to some peers. But machines with multiple physical interfaces are very likely to have policy routing (ip rule) support anyway. So far, the only OS I know of that needs this feature is ChromeOS (crostini). Fixes #245. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Brad Fitzpatrick	765695eaa2	net/netns: also don't err on tailscaled -fake as a regular user That's one of my dev workflows.	5 years ago
Brad Fitzpatrick	7f68e097dd	net/netcheck: fix HTTPS fallback bug from earlier today My earlier `3fa58303d0` tried to implement the net/http.Tranhsport.DialTLSContext hook, but I didn't return a *tls.Conn, so we ended up sending a plaintext HTTP request to an HTTPS port. The response ended up being Go telling as such, not the /derp/latency-check handler's response (which is currently still a 404). But we didn't even get the 404. This happened to work well enough because Go's built-in error response was still a valid HTTP response that we can measure for timing purposes, but it's not a great answer. Notably, it means we wouldn't be able to get a future handler to run server-side and count those latency requests.	5 years ago
Brad Fitzpatrick	1407540b52	net/netns: don't return an error if we're not root and running the tailscale binary tailscale netcheck was broken otherwise. We can fix this a better way later; I'm just fixing a regression in some way because I'm trying to work on netcheck at the moment.	5 years ago
David Anderson	5114df415e	net/netns: set the bypass socket mark on linux. This allows tailscaled's own traffic to bypass Tailscale-managed routes, so that things like tailscale-provided default routes don't break tailscaled itself. Progress on #144.

Brad Fitzpatrick	3fa58303d0	netcheck: address some HTTP fallback measurement TODOs	5 years ago
Brad Fitzpatrick	7247e896b5	net/netcheck: add Report.IPv4 and another TODO	5 years ago
David Anderson	e9f7d01b91	derp/derphttp: make DERP client use netns for dial-outs.	5 years ago
Brad Fitzpatrick	9e3ad4f79f	net/netns: add package for start of network namespace support And plumb in netcheck STUN packets. TODO: derphttp, logs, control. Updates #144 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	0245bbe97b	Make netcheck handle v6-only interfaces better, faster. Also: * add -verbose flag to cmd/tailscale netcheck * remove some API from the interfaces package * convert some of the interfaces package to netaddr.IP * don't even send IPv4 probes on machines with no IPv4 (or only v4 loopback) * and once three regions have replied, stop waiting for other probes at 2x the slowest duration. Updates #376	5 years ago
Avery Pennarun	7cd9ff3dde	net/netcheck: fix race condition initializting RegionLatency maps. Under some conditions, code would try to look things up in the maps before the first call to updateLatency. I don't see any reason to delay initialization of the maps, so let's just init them right away when creating the Report instance. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago

David Anderson	657f331e8b	net/dnscache: remove unnecessary lint warning.	5 years ago
Elias Naur	ad0795efc2	net/dnscache: don't use the Go resolver on Android The local resolver is not available for apps on Android. Signed-off-by: Elias Naur <mail@eliasnaur.com>	5 years ago
Brad Fitzpatrick	2244cca5ff	net/tlsdial: update package doc to say it's now somewhat useless	5 years ago
Brad Fitzpatrick	172d72a060	Revert "net/tlsdial: add memory-optimized TLS cert verification path for iOS" This reverts commit `6fcbd4c4d4`. Decided to put it in tailscale/go's crypto/x509 instead.	5 years ago
Brad Fitzpatrick	6fcbd4c4d4	net/tlsdial: add memory-optimized TLS cert verification path for iOS Behind a build tag for now.	5 years ago
Brad Fitzpatrick	b6fa5a69be	net/tlsdial: add package for TLS dials, and make DERP & controlclient use it This will do the iOS-optimized cert checking in a following change.	5 years ago

David Crawshaw	41ac4a79d6	net/nettest: new package with net-like testing primitives This is a lot like wiring up a local UDP socket, read and write deadlines work. The big difference is the Block feature, which lets you stop the packet flow without breaking the connection. This lets you emulate broken sockets and test timeouts actually work. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
Brad Fitzpatrick	023df9239e	Move linkstate boring change filtering to magicsock So we can at least re-STUN on boring updates. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	5c1e443d34	wgengine/monitor: don't call LinkChange when interfaces look unchanged Basically, don't trust the OS-level link monitor to only tell you interesting things. Sanity check it. Also, move the interfaces package into the net directory now that we have it.	5 years ago

Brad Fitzpatrick	2cff9016e4	net/dnscache: add overly simplistic DNS cache package for selective use I started to write a full DNS caching resolver and I realized it was overkill and wouldn't work on Windows even in Go 1.14 yet, so I'm doing this tiny one instead for now, just for all our netcheck STUN derp lookups, and connections to DERP servers. (This will be caching a exactly 8 DNS entries, all ours.) Fixes #145 (can be better later, of course)	5 years ago
